## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vextorium-dex-protocol-volume-34a29721 -d '<json body>'
```

Example prompt: What's Uniswap's trading volume over the last 24 hours, 7 days, and 30 days, and what share of total DEX volume does it hold right now?

## When to prefer this

Use this endpoint when you need volume metrics for a specific DEX protocol by name and want multi-timeframe coverage (24h through 1y) plus market share context — especially when DefiLlama is the preferred data source. Prefer this over general on-chain queries when you need aggregated cross-chain volume rather than per-transaction data.

## Known failure modes

- Unknown or misspelled DefiLlama slug returns empty or error response
- DEX not indexed by DefiLlama results in null fields
- Protocol with very low volume may return null for certain time-range fields
- Stale data if DefiLlama pipeline is delayed
- Network timeout on POST request

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

A JSON object containing the DEX name, its token ticker, the blockchain networks it operates on, and volume figures in USD for 24h, 7d, 30d, 1y, and all-time historical periods, plus the 24-hour percentage change and its share of total DEX volume in the last 24 hours. Data is sourced from DefiLlama.
